SOLUTION

From the numbers given 2, 3, 4,6, 7, 8, 9, 10, and 11, the total number of cards will be 9, which is the total number of cards.

The cards with prime numbers are the ones with 2, 3, 7, and 11. Which is a total of four cards.


\text{Probability = }\frac{\text{expected outcome }}{\text{total outcome}}

So, the probability of picky a prime number becomes


\text{Probability =}(4)/(9)
